The ph of the solution would be 8
Divide by 1000
145÷1000=0.145
Hope this will be helpful.
Answer:
C5H12 + 8O2 --> 5CO2 + 6H2O
Explanation:
Complete question
Write a balanced chemical equation to represent the combustion of CH3CH2CH2CH2CH3
Solution
The given compound is pentane
C5H12
The empirical equation representing combustion of pentane is
C5H12 + O2 --> CO2 + H2O
We will first balance the carbon atoms
C5H12 + O2 --> 5CO2 + H2O
Now we will balance the Hydrogen molecule
C5H12 + O2 --> 5CO2 + 6H2O
Now we will balance the oxygen molecule
C5H12 + 8O2 --> 5CO2 + 6H2O
Given a sample of three unknown solids, we would be able to deduce which are ionic solids by their melting and boiling points, conductivity in water, and the insulation they provide.
<h3>What are Ionic solids?</h3>
- An ionic solid is a solid formed by ionic bonds.
- They are the solid version of ionic compounds, which are held together by strong electrostatic energies.
<h3>What properties do they possess?</h3>
- Among their many properties, ionic solids possess high melting and boiling points.
- These solids are also known to conduct electricity well <em><u>when </u></em><em><u>dissolved </u></em><em><u>into </u></em><em><u>water</u></em>, however, this can be tested after melting them as they <u>will not conduct electricity in a solid state</u>.
- A final property that we can use to identify them is that they provide a good means of insulation.
- Each of these properties can be tested and will allow us to determine the ionic solids amongst the samples.
Therefore, we can find the ionic solids amongst the samples by testing their melting and boiling points, conductivity in water, and the insulation they provide, given that each of these should provide high values to indicate an ionic solid.
